Logos offer free marketing and add value to products. You may not be able to afford the $4,000 Saint Laurent biker jacket, but you can have Hedi Slimane’s $200 Saint Laurent T-shirt which has been redesigned by the artist Zane Reynolds for spring.

He has been called “the single most influential men’s designer this century.” Recall the skinny suit, which seemed to define the trajectory of men’s – and women’s – silhouettes in the new millennium? It was, by most accounts, Hedi Slimane’s invention.

His advertising campaigns for the Yves Saint Laurent fragrances Opium (with a red-haired Sophie Dahl completely naked wearing only a necklace and stiletto heels in a sexually suggestive pose) and YSL M7 (with martial arts champion Samuel de Cubber in complete full-frontal nudity) have been famous and provocative by pushing fragrance ads to a new level of creativity in artistic expression and commercial impact.

Josephine Skriver is one of the industry’s most in-demand faces. Her big fashion break came during the autumn/winter 2011 shows in Milan, where she began her catwalk career by opening the Alberta Ferretti show and closing the Prada show. Also in 2013, she joined the ranks of the Victoria’s Secret models at the brand’s multi-million-dollar catwalk show in November 2013, and became a face of Yves Saint Laurent alongside fellow VS alumnus Cara Delevingne and Jourdan Dunn.
